PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent N 0. 474,032, dated May 3, 1892. Application filed September l0 1891. Serial No, 405,358- (No model.)

To all whom it may concern.-

Be it known that I, LOUIS l/V. SOUTHGATE, a citizen of theUnited States,residing at Worcester, in the county of \Vorcester and State of Massachusetts, have invented a new and useful Improvement in Printing-Presses, of which the following is a specification.

The aim of this invention is to carry out the improvement shown, described, and claimed in my application, Serial No. 402,947, filed August 17, 1891, so that three webs may be printed, associated, and folded, as hereinafter described.

To this end the invention consists of the device described and claimed in this specification, and illustrated in the accompanying drawings, in which- Figure 1 is a diagrammatic view of the press and folder mechanism, showing how the webs are printed, associated, and folded. Fig. 2 is a plan of the web-turner. Fig. 3 is a side elevation of what 1 term the web-reverser. Fig. l is a plan of the device shown in Fig. 3; and Figs. 5, 6, and 7 are diagrams illustrating the arrangement of plates and the way in which twelve, ten, and six. page papers are printed and folded.-

Referring to the said drawings and in detail, A and B represent two type-cylinders geared to run synchronously in opposite directions. Mounted vertically above and below the type-cylinder A are the impressioncylinders C and D, and vertically above and below type-cylinder B are similarly-arranged impression cylinders E and F. Arranged horizontally on each side of each type-cylinder are suitable inking devices G G, which will thus ink the type-cylinders, so that the same will print in connection with each impression-cylinder. Two rolls of paper II and I are mounted at one side of the printing mechanism, as shown, so that two webs or a double web a and b may be drawn from said rolls II and I. The web a from the roll II is drawn down under roll 2 and then unites with web I) from the roll 1, and the double web thus formed passes over roll 3 and then between impression-cylinder C and type-cylinder A. From here the double web runs around roll 4, impression-cylinder E, thus in contact with type-cylinderB, and then overroll 5 to roll 6. At this point the web a is turned back over roll 7 into the reverser, hereinafter to be described, and is turned under web I). From the roll 6 the double web runs around the rolls 8 and 9 and impression-cylinder D, and thus again in contact with the type-cyL inder A. From impression-cylinder D the webs are divided, the web ct going up over roll 10 and across to roll 11, while the Web Z) goes through a turner, then to roll 12, and then reunites with the web a. The double web then passes around impression-cylinder F and thus in contact with type-cylinder B, then around rolls 13 and 14 to the cutting or perforating cylinders J and K, and then by belts l5 and 16 to the cylinders 17 and 18. Arranged below said cylinders 17 and 18 is a switch N, of any of the usual constructions, which may be set to alternately switch the sheets to the former folders L and M, arranged back to back. Arranged below the formers are the presserrolls of usual construction, and also cutting and folding cylinders, as shown, and as described at length in my companion application before referred to. The reverser consists of the roll 7, the two parallel forty-fivedegree turner-bars 19 and 20, and parallel cylinder 0. The web a is carried back over the roll 7, out over turner-bar 19, over parallel cylinder 0, back in up over turner 20. This will simply place web a under the web I) as the webs are then traveling and will not turn either web. The turner consists of the turner-bars 21 and 22, arranged atforty-five degrees to the travel of the web and at right angles to each other and of the parallel cylinder 0. This turner is of the ordinary construction, and the same is used to turn web 19 over in the usual manner.

All the mechanism so far described is substantially the same as described and claimed in my companion application before referred to and will not be further described in this case, except to state that by using the same two oppositely-disposed eight or two oppositely-disposed SlX page papers maybe printed and folded, or four four-page papers oppositely or not may be printed and folded at every revolution of the type-cylinders.

The requirements of modern newspaperwork rarely call for more than an associated twelve-page paper. If a fourteen, sixteen, or larger paged paper is required, the best and the common way of producing the same is to run the press twice or to print parts of the paper on different presses, and to associate the products independently of the printing and folding mechanism.

The aim of this invention is to enlarge the capacity of the mechanism described in my former application, so that the same will produce also a twelve or ten page paper. To do this, I add another printing mechanism or a third web and associate the webs, as hereinafter described. A preferred arrangement of these instrumentalities is shown, and the same consists of a printing mechanism mounted under that previously described. Of course a web previously printed could be associated with the other webs; but the preferred way is to print all the webs at the same time. My arrangement consists of the oppositely-running type-cylinders S and R and the impression-cylinders P and Q. A roll of paper H is mounted on the same side of the machine as the rolls H and I, and a web 0 is drawn from the same. This web passes around roll 23 and impression-cylinder Q, and thus in contact with type-cylinder S, where one side is printed, then around roll 24 and impression-cylinder P, and thus in contact with the other typecylinder R, where the second side is printed and the web perfected. From the impressioncylinder P the web a is carried around rolls 25 and 26 and brought into contact with or associated with web I). A slitter 27 is mounted so that the same may be used in connection with the roll 26 for a purpose described to slit the web 0. When the web cis used,webs b and a both go to the turner and here, as shown in Fig. 2, the webs b and cl are both lead over the same,thereby web 0 is turned up over web I) as the webs are then traveling, and thus the supplemental web a will issue from the printing mechanism between webs a and 1). Sometimes it is not advisable to run all the webs between the impression-cylinder F and type-cylinder l3, and when this is the case the web I) or the webs b and c, as it happens, may be run out under impression-cylinder F, up over roll 28, and associated with web a on roll 14, as indicated in dotted lines in Fig. 1. It is evident, also, that the web 0 may be associated with web I) at any point beyond impression-cylinder D, and also that the turner may be located at any point in the travel of the webs between impression-cylinder D and the folder.

The operation will now be described, and the case of a twelve-page paper will first be considered, and reference should be had to Fig. 5 to understand this operation. Fig. 5 shows at the top the disposition of plates on the cylinders developed into plan, and the left-hand column shows the first or leading part of the webs and the right-hand column shows the following or last part of the webs printed, and at the bottom of the figure is indicated how the associated webs are folded. It may also be noted that when the webs come the second time in contact with the type-cylinders that the second set of plates on the typecylinders will print on the webs over the pages previously printed by the first set of plates, and vice versa. Vebs 0; and b are first presented to type-cylinder A,where pages two and eleven and eight and five are printed on web d. Then the webs are presented to cylinderB, and pages seven and six and one and twelve are printed on web I). Now the web a is next turned under web I), or the Webs are reversed. The webs are again presented to cylinder A and pages eight and five and two and eleven printed on web I). The web 0 is now added. This web 0 as printed consists of oppositelydisposed four-page papers, which will form the second leaf of the product,or pages three and four and nine and ten. The webs b and 0 now pass through the turner, and this will place web 0 on top of web I), as the webs are then moving. Webs Z) and cnow unite with web a, and web a is now presentedv to typecylinder B, and pages one and twelve and seven and six are printed on the same. The associated product will now consist of oppositely-disposed twelve-page papers. The three webs are now led through the cutting or perforating cylinders J and K, which perforate the webs, then into the bite of the cylinders 17 and l8,which will pull the sheets from the webs, and these associated sheets are alternately switched to each former folder and oppositely folded, as indicated in Fig. 5. Thus two twelve-page papers are printed at every revolution of the type-cylinders. For a tenpage paper one of the webs is run half the width of the other webs and the half-width web is preferably the supplemental web 0. When the web 0 is half-width, the operation is the same as when twelve-page papers are printed and may be easily followed by the diagram in Fig. 6. The product will be folded as shown in the bottom of the figure. Thus two ten-page papers can be printed at every revolution of the type-cylinders. Toprint an eight-page paper, the webs a and I) only may be used, and the operation then will be the same as described in my application before referred to, or, again, a single web maybe printed by the cylinders A and B and asso-.

ciated with web 0 to form alternately or regularly disposed eight-page papers. During either of the above-described operations of course the third web could also be printed and carried out of the press and thereafter handled as desired. hen the product consists of papers all disposed the same way on the webs, the cylinders J and K are rendered inoperative, and the associated product led over the formers or a single former and the cutting mechanism under the formers is used, the foldingmechanism being run at a slightlydecreased speed. This operation is set forth at length in-my companion application before referred to. For the fast printing and ITO folding of six-page papers the folder is set as last described and all three webs are used. Web 0 is slit by the slitter 27, and the web a and one-half of the web 0 is led over one former and the web and the other half of the web 0 is led over the other former. This op eration may be easily followed by reference to Fig. 7 and results in four six-page papers at every revolution of the type-cylinders. A six-page paper can also be printed by running any two of the webs as a half-width webas, for example, the webs a and b-and as described at length in my other application; also, the web 0 may be associated with a web printed on the cylinders A and B, either being half-width, as desired, and this product may be oppositely disposed or not, as desired, and may be folded by the folder. For a fourpage paper one web may be run and printed, so as to form alternately-disposed papers or not, and the paper can be properly folded by the folder previously described. The pre ferred way to produce four-page papers is to run any two of the webs and then lead one web over one former and the other web over the other former, so as to print four four-page papers at every revolution of the type-cylinders. When webs a and b are the webs to be used in this operation, the manner of printing the same is described in my former application. In all cases where only two of the webs are being delivered to the folder described the third web could be printed and run outside the machine and thereafter handled, as desired. Thus six four-page papers could be printed at every revolution of the type-cylinders. lVhen only one web is to be used in connection with type-cylinders A and B, the preferred arrangement is to lead a web, as at (Z,

Fig. 1, over rolls 4, 6, 8, and 9 to the lower impression-cylinders, which are always set in register with each other. During this operation impression-cylinders O and E are moved away from the type-cylinders and two of the inking apparatuses G are thrown out. Thus I have invented a machine which will printand fold either two twelve-page, two ten-page, two eight-page, four six-page, or four fourpage papers, as desired, for every revolution of the type-cylinders, and, further, the machine is one of single width, and the number of plates during the aforesaid operations is kept at a minimum.

Modifications of the arrangements herein shown may be made bya mechanic skilled in designing printing-press machinery without departing from the scope of my invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1.
